Web technologies are gaining increased importance in automation control systems, especially in slow control systems. Alternatively, the requirements to exchange the complex data between the cooperating applications and the applications-based non-Microsoft Platforms are widely increasing in the industrial systems. The applications-based OPC (OLE for Process Control) technique to exchange data between the measurement and control systems on plant floor with XML leverages are proposed in the OPC XML DA (Data Access) Specification. Moreover, we are expecting a system that allows easily aggregating the existing productions and maintenance managements with new products as frameworks. This system also allows exchanging the data between collaborating applications in horizon. Besides, the high performance and the ability to read and decode any type of the data from measurement and control systems are important factors in the application design. This paper introduces new control system aspects that are used for the design of slow control systems. In general, they are based on the OPC and XML technologies. Main aspects are the throughout of standards for interfaces, functionalities and architectures. To guarantee the security problems in system, this paper also discusses the levels of the security in automation and control systems. These discussions provide more security solutions for technical-level readers.
